In Martial Universe, Signed in at the Start with Yao Lao's Ring

Eight Extremes Collapse—an advanced Xuan-rank Dou Technique, a close-combat martial art renowned for its immense offensive power.

When trained to mastery, each strike carries eight layers of force, with each layer stacking upon the next. At its peak, its destructive power can rival that of a low to mid-level Creation Martial Art.

The moment Yao Lao mentioned the name Eight Extremes Collapse, Lin Yan's mind raced with information about this technique.

His eyes flashed with excitement.

After all, Eight Extremes Collapse was an advanced Xuan-rank martial art, and since the power system of Wu Dong Qian Kun closely matched that of Battle Through the Heavens, Lin Yan could roughly deduce an equivalence:

Ancestor Realm ≈ Dou Emperor Realm.

By that logic, martial arts and Dou Techniques should follow a similar power scale.

In Wu Dong Qian Kun, martial arts were divided into Nine Grades, with Creation Martial Arts existing above them.

The novel described Creation Martial Arts as:

"The might of such martial arts is truly capable of shaking the heavens and the earth!"

This description closely resembled how Battle Through the Heavens described Earth-rank Dou Techniques.

From this, Lin Yan concluded:

Creation Martial Arts ≈ Low to Mid-level Earth-rank Dou Techniques.

If that were the case, then an advanced Xuan-rank Dou Technique like Eight Extremes Collapse should be equivalent to a high-grade Nine-Golden Martial Art in Wu Dong Qian Kun.

That realization alone made Lin Yan's blood boil with excitement.

Just moments ago, he had been training in a mere Grade 1 Martial Art, Penetrating Fist.

And now, Yao Lao was about to teach him a Grade 9 Martial Art, a technique that, if mastered, could even rival Creation Martial Arts.

How could he not be ecstatic?

"Senior Yao, I sincerely thank you for this opportunity!"

Lin Yan didn't hesitate. He immediately cupped his fists in gratitude, accepting the offer without a second thought.

He even thanked Yao Lao beforehand, fearing that the old man might change his mind.

Seeing this, Yao Lao couldn't help but laugh.

"Alright, alright. Since you're so eager, let's begin."

"I will first impart to you the fundamental principles of Eight Extremes Collapse."

"But for now, just memorize them—don't rush into practicing it yet."

"Although Eight Extremes Collapse doesn't have strict Yuan Power requirements, and you can technically begin learning it even without much Yuan Power, it does place immense strain on the physical body."

"Right now, you've only reached the fourth layer of the Tempered Body stage. Your body is still too weak. If you attempt to use Eight Extremes Collapse recklessly, you could end up seriously injuring yourself instead."

Lin Yan listened carefully, fully accepting Yao Lao's advice.

In fact, he felt relieved.

Thankfully, Eight Extremes Collapse didn't require a high level of Yuan Power to get started. Otherwise, with his current strength at only the fourth layer of Tempered Body, he wouldn't even be able to attempt learning it.

"Next, we'll need to strengthen your physical body."

Yao Lao's smile widened.

Seeing that expression, Lin Yan suddenly had a very bad feeling.

"How… exactly will I be training?" he asked cautiously.

Yao Lao's grin deepened.

"Simple. You're going to get beaten up."

"The heavier the beating, the better. We'll push your body to its absolute limit, and once you're covered in wounds, we'll use medicinal liquid to heal and reinforce your physique."

Lin Yan's mouth twitched.

But in order to grow stronger, he gritted his teeth and nodded.

"Senior Yao, I'll leave it to you!"

Thus, the brutal training began.

In the courtyard, Lin Yan stood like a wooden stake, his feet planted firmly on the ground.

Floating behind him, Yao Lao's soul form hovered in midair, observing with a calm expression.

Then, with a flick of his finger—

Pa!

The air trembled slightly, and a whip-like force constructed from pure Yuan Power struck Lin Yan's back.

A red welt immediately appeared on his skin.

Lin Yan gritted his teeth, his face twitching from the pain.

But he knew this training was crucial for his growth, so he endured it without complaint.

"Again!" he shouted.

Yao Lao's eyes gleamed with approval.

"Good!"

Pa! Pa! Pa! Pa!

The training continued.

Yao Lao precisely controlled his strikes, ensuring that each attack hit Lin Yan's physical limit without causing internal injuries.

This method pushed Lin Yan to his breaking point while allowing his body to gradually adapt and grow stronger.

At first, Lin Yan struggled to endure the pain.

But as time passed, he started to withstand the blows without flinching.

Seeing this, Yao Lao raised an eyebrow in mild surprise.

'This kid's endurance… is far beyond ordinary.'

Finally, as the sun began to set, Yao Lao halted the training.

Looking at Lin Yan, who was now covered in bruises and wounds, Yao Lao nodded with satisfaction.

"That's enough for today."

"Training is thirty percent effort, seventy percent recovery. If you don't replenish your body after such intense training, you'll end up with permanent injuries instead of progress."

"During today's training, I happened to sense a demonic beast in the back mountain. I knocked it unconscious earlier, so we'll be having beast meat for dinner tonight."

Lin Yan, exhausted, simply nodded.

He had planned to cook, but Yao Lao pressed him back down.

"I'll handle it this time."

After a hearty meal and a period of rest, Lin Yan returned to his room to soak in the medicinal bath.

Initially, his body had still retained some leftover medicinal energy from his previous sessions.

However, after today's insane training regimen, every bit of that energy had been completely burned away.

Right now, soaking in fresh medicinal liquid was the optimal way to recover.

"Ahhh…"

Lin Yan let out a deep breath as he sank into the wooden tub, a wave of comfort washing over him.

His body, battered and bruised, absorbed the medicinal energy like a dry sponge.

Relaxing in the warm water, exhaustion overtook him, and before long—

He fell into a deep sleep.

Over the next few days, Lin Yan continued this brutal training routine.

The results were astonishing.

His Tempered Body stage advanced at an incredible pace.

Originally, he had only reached the fourth layer.

But through his relentless efforts, he advanced one layer every few days.

Now, Lin Yan had successfully broken through to the sixth layer of the Tempered Body stage.

His physical strength had skyrocketed, and his body had even begun generating its first trace of Yuan Power, allowing him to use basic Yuan techniques.

At the same time, his mastery of Eight Extremes Collapse had improved significantly.

Though he was still far from perfection, he had officially reached the entry-level stage of the technique.

His progress was nothing short of extraordinary.

At this point, Lin Yan was absolutely confident—

Among the younger generation of the Lin Clan, no one could rival him anymore.

However, today, he did not continue training.

He had completely exhausted his supply of medicinal liquid.

So, Lin Yan decided to head to the Lin Clan's back mountain in search of more herbs.

After searching for most of the day without success, he suddenly noticed a group of Lin Clan disciples surrounding a girl.

"Well, well… Isn't this a Scarlet Sun Herb?"

"Qingtan, did you steal our spirit herb from the back mountain?"

At the front of the group stood Lin Shan, his arms crossed, sneering at the girl.
